If you eat a lot of meat and bike, you could potentially have a bigger carbon footprint than a very fuel efficient vehicle.

That's what I hoped this article was about when I saw the headline. I was disappointed it was only about the $ cost of food and not the externalities. Thanks for sharing. It's interesting to see though that a biking paleo dieter is still 2x as efficient from a passenger-mile standpoint as a roughly average 25 mpg vehicle, and the average US diet is still better than a double occupancy Prius.

  This is a really important point. For many people, bike commuting is partly a way to avoid having to schedule an extra hour a day dedicated solely for exercise, so the calories are indeed "free"
